PROBLEM TO BE SOLVED: To accurately calculate a cycle ratio or the like even from a signal having no clear peak.

SOLUTION: The method includes a phase calculation step of determining, with respect to each of a plurality of signals based on repetitive rhythmics associated with a voluntary motion of a living body, a change amount of phase in a fixed time; and a ratio calculation step of calculating a ratio of phase change quantity for each of the plurality of signals calculated in the phase calculation step.
